Bit 09
:
RX FIFO Almost Full
– When this bit is high (1), the RX FIFO has been
almost full one or more times. This bit is latched. Once set, it
must be cleared by writing a zero to this bit location. The
assertion of the RX FIFO Almost Full bit indicates the
receiver circuit is operating at maximum capacity. If it does
occur, the PCI bus master should temporarily suspend all
write and read operations to the board.
Bit 08:
Bad Data
– When this bit is high (1), the receiver circuit has detected
invalid data one or more times. This bit is latched. Once set, it
must be cleared by writing a zero to this bit location.
Bit 07:
Pending Net. Int. 4
– When this bit is high (1), one or more type 4 network
interrupts have been received. To see the sender data and
sender node ID, read the Interrupt Sender Data 4 (ISD4) FIFO
at offset $38 and the Interrupt Sender ID (SID4) at offset $3C
respectively.
Bit 06:Rogue Packet Fault
- When this bit is set high (1), the board is operating as
either Rogue Master 1 or 0 and has detected and removed a
rogue packet. This bit is latched. Once set, it must be cleared
by writing a zero (0) to this bit location.
Bit 05:TX FIFO Full
- When this bit is high (1), the TX FIFO has been full one or
more times. This bit is latched. Once set, it must be cleared by
writing a zero (0) to this bit location. This is a fault condition
and data may have been lost.
NOTE
This condition should not occur during normal operation. Bit 05 is for diagnostic purposes only.
Bit 04:
Reserved
- This bit is reserved.
Bit 03:
Reset Node Request
– When this bit is high (1), another node on the
network has requested that the local PCI bus master reset this
board. The RFM-5565 does not reset itself automatically.
Bit 02:
Pending Net. Int. 3
– When this bit is high (1), one or more type 3 network
interrupts have been received. To see the sender data and
sender node ID(s), read the Interrupt Sender Data 3 (ISD3)
FIFO at offset $30 and the Interrupt Sender ID (SID3) FIFO at
offset $34 respectively.
Bit 01:
Pending Net. Int. 2
– When this bit is high (1), one or more type 2 network
interrupts have been received. To see the sender data and
sender node ID(s), read the Interrupt Sender Data 2 (ISD2)
FIFO at offset $28 and the Interrupt Sender ID (SID2) FIFO at
offset $2C respectively.
Bit 00:
Pending Net. Int. 1
– When this bit is high (1), one or more type 1 network
interrupts have been received. To see the sender data and
sender node ID(s), read the Interrupt Sender Data 1 (ISD1)
